EAW Two-Part Sub Bases, Picatinny

• Two-part base design: The separate front and rear bases keep the mounting area open and give more flexibility around the action, which is useful on rifles that need model-specific base geometry without adding unnecessary bulk.
• Picatinny lower interface: Built to fit a wide range of Picatinny-equipped rifles, these sub bases provide a solid starting point for a repeatable optic setup and make it easier to move within established rail-based platforms.
• EAW Ø 7 mm interface: The upper interface is made for compatible EAW components, allowing the mount to be integrated into the EAW system rather than treated as a generic base, which helps maintain a consistent fit across matched parts.
• Aluminium construction: The aluminium body keeps weight down compared with heavier all-steel alternatives, helping preserve rifle balance while still providing the rigidity needed for everyday field and range use.
• Made in Germany: German manufacture reflects EAW’s focus on precise machining and tight tolerances, which matters in scope mounting because secure alignment is essential for stable zero and dependable return to position.

About the - Series

EAW mounting systems are built around the idea of giving rifle owners a secure, model-specific connection between firearm and optic. Within the company’s broader lineup, these mounts serve hunters, sport shooters and professional users who need a solution matched to the rifle rather than a one-size-fits-all base. The emphasis is on precise fit, dependable clamping surfaces and a mechanical layout that supports repeatable optic positioning in real use.

Across the range, EAW is known for offering different mounting concepts for different applications, including classic hunting mounts and more modern tactical-oriented designs. What ties the family together is a focus on stable interfaces, clean machining and compatibility within the EAW ecosystem. In practice, that means a shooter can choose the mounting style that suits the rifle and optic combination while still staying within a system designed around durability, alignment and practical serviceability. For users who want a base that supports a structured mounting setup rather than an improvised combination of parts, EAW two-part bases fit that philosophy well.

About the EAW Two-Part Sub Bases, Picatinny

The EAW Two-Part Sub Bases, Picatinny are a model-specific mounting solution for rifles that use a Picatinny rail as the lower attachment standard while connecting to compatible EAW upper components through the EAW Ø 7 mm interface. This makes them particularly useful for shooters who want to stay within the EAW mounting system while working with rifles and platforms that already rely on Picatinny geometry. The two-piece layout keeps the base arrangement compact and practical, especially where receiver shape, loading access or rifle handling benefit from separate front and rear elements rather than a full-length one-piece base.

Because these bases are made from aluminium, they reduce unnecessary weight on the rifle without moving away from the rigid structure expected from a precision mount component. That matters on hunting rifles and crossover sporting setups where added mass over the action can affect balance and carrying comfort. The black finish gives the bases a low-profile appearance that matches modern optics and rifle hardware without drawing attention away from the rest of the setup.

Compatibility is a major strength here. These sub bases are intended for use with a broad list of rifles and platforms, including models from Accuracy International, Anschutz, Baikal, Benelli, Beretta and CZ. In practical terms, that wide fitment makes them a useful choice for shooters building a rifle-specific optic mount while retaining the modular logic of the EAW system.

About EAW

EAW was founded by Ernst Apel in Würzburg, Germany, in 1919. The company developed and produced its first riflescope mounts in 1945, and since 1951 mount development and production have been its main focus. That long specialization is central to EAW’s reputation in the optics-mounting field, where precise fit and mechanical repeatability matter as much as the optic itself.

Today, Ernst Apel GmbH is headquartered in Eibelstadt, Germany, following the company’s move in 1970 from Würzburg to Gerbrunn. EAW is best known for making pivot mounts, slide-on or roll-off mounts, and claw mounts for riflescopes, while also offering thermal imaging devices and more recent tactical mounting solutions. For products such as scope bases and mounting components, EAW’s identity is rooted in German manufacturing and a long-standing focus on dedicated rifle-optic interfaces.
